[Variant]

HI all ...

This morning my daughter switched on the tv , but 10 sec later she was in our sleeping room ..
The tv was dead she said ..
Indeed , i checked it and there was no picture or sound ..
When the tv is switched on there is sound for a short while then the tv goes to stand by .
I think the HS supply is ok because the familiar hisssss when switching on is still there ..
circuit board number is MC 017 A..

Please advise.

Kind Regards ..

Gert.
